A blood stem cell donation can save the lives of people with leukemia. To collect these cells from the bloodstream, donors are given medication that mobilizes blood stem cells from the bone marrow. A pilot study now suggests that physical exercise could specifically support stem cell donation.
A new editorial in Osteoporosis International, “Beyond the fracture: coordinated action for bone health equity in Africa,” sets out a roadmap to address osteoporosis and fragility fractures across the continent. The paper is authored by members of the International Osteoporosis Foundation (IOF) Board of Governance from the African region. The editorial warns that alarmingly high post-fracture mortality reaches 20–30% across the continent and that hip fractures alone are projected to double by mid-century. Despite the evidence of rising fracture burden, preventable disability, and premature mortality, bone health remains largely absent from national health priorities, medical training, and health system planning across most of Africa.
A fluid that women with advanced ovarian cancer know all too well — ascites, the buildup of liquid in the belly — may be doing more than causing discomfort. A federally funded Duke University School of Medicine study finds this fluid helps cancer cells survive and spread – and that a decades-old cholesterol drug may be able to disrupt that protection.
Researchers have discovered a “control switch” inside our immune cells that helps the body destroy dangerous fungal infections.
The team found that a protein called RAB5c helps white blood cells kill Aspergillus fumigatus – a common airborne fungus that can cause life‑threatening lung infections in people with weakened immune systems.
The study reveals that without this protein, immune cells are effectively disarmed – even though they appear to be attacking at full force.
The findings could have major implications for treating fungal infections – which are notoriously hard to diagnose and often resistant to drugs.
The team hope their breakthrough could lead to new treatments for vulnerable patients.
Pre-eclampsia is one of the main causes of death in pregnant women. Researchers from China conducted a large multicenter retrospective study involving 53,054 singleton pregnancies in China and identified that elevated blood glucose levels in the first trimester and significant gestational blood glucose fluctuations increase the risk of pre-eclampsia in a U-shaped pattern. These findings provide new evidence for optimizing gestational glucose monitoring strategies, highlighting the need for enhanced blood glucose management.
